more AP with the raptor but if you have tota+8 and impact+8 I think its better cause of the 160 elemental
if you go for raptor+8 buy a MS+7-8 for people with too much spear def
if you go for dual wield: not much people have spear and club def and if yes you have 160 elemental to compensate. also the combo is easier and you have the same range
